[flexcoders] (Cairngorm App) Advice on Deleting a VO, from a DataGrid containing an Array of VO's

[Bjorn Schultheiss]

Hey Mike,   I’ll give you a quick answer.   Create an event with the index that is to be removed. In your command call your server-side method and pass the index as param (also it may be useful to tack the index on the call object), On confirmation of this process, in the result handler then update the model object via the modelLocator.   Is this understandable?   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Mike Anderson Sent: Wednesday, 18 October 2006 9:51 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] (Cairngorm App) Advice on Deleting a VO, from a DataGrid containing an Array of VO's   Hello All, I have a Cairngorm-based application. On a particular screen within this App, I have a Products DataGrid with a DataProvider (from my Model) assigned to it. The variable from my Model, is "productsList" - which is an ArrayCollection populated with ProductVO's returned from the CF Server. With any typical Cairngorm Application, you assign your DataProvider properties to the Model Variables - in order to keep everything centralized & controllable. If I have a Row selected in this DataGrid, and I want to delete this particular Record, what is the best way to accomplish this? On the surface, this sounds like a really simple/stupid question - BUT, there is more to it than that. I want to make sure that I'm doing this in a politically correct manner - following the rules of well-written application practices. Instead of simply blowing away the Record from the DataGrid, I want to broadcast a Cairngorm Event, which removes the ProductsDataGrid 'selectedItem' (as a VO possibly??) from the "productsList" ArrayCollection. Since the "productsDataGrid.dataProvider" is bound to "model.productsList", the changes will obviously be reflected in the DataGrid, once I remove the item from the ArrayCollection. BUT, I don't want this to happen, until I get a validated "True or False" response from the ColdFusion Server - otherwise, I will get potential consistency issues. Like - if the server is unreachable at the moment. It would be confusing to the User, if the record got deleted from the DataGrid, but not from the actual DataBase. What would be the best "Full Circle" solution, to attack this problem? Thanks in advance, for any advice on this.
